Abstract

The invention provides a system and method for imaging in organism tissue. The system comprises an ultrasonic wave unit, a quantum dot and a detection unit, wherein the ultrasonic wave unit is used for outputting ultrasonic waves and generating photosignals of sonoluminesence, the quantum dot is used for converting the photosignals generated by sonoluminesence into infrared signals and is pre-embedded inside the organism tissue, and the detection unit is used for detecting and recording the infrared signals to complete three-dimensional imaging. Through an ultrasonic probe, the organism tissueis induced to generate the photosignals of the sonoluminesence, then the photosignals are converted into infrared lights, and by collecting the infrared lights, three-dimensional imaging of the inside of the tissue is completed. When imaging is conducted inside the organism tissue, the measuring depth can be guaranteed, and high resolution can be reached.

Description

Technical field [0001] The invention relates to the field of medical devices, in particular to a system and method for imaging in biological tissues. Background technique [0002] Due to its opaque and heterogeneous nature, biological tissues cannot be directly imaged inside. Diffusion optical tomography (Diffuse Optical tomography or OpticalDiffusion Tomography, DOT / ODT) can be developed through the development of highly sensitive near-infrared photon detection instruments and image reconstruction technology based on the photon transport model of biological tissues. Retrieve the three-dimensional distribution of the internal optical characteristic parameters of the tissue from the measurement information of the time, space and spectral distribution of the surface diffused light under multi-point excitation, and correlate it with the physiological state of the tissue, and X-ray, ultrasound and magnetic resonance Compared with other conventional imaging methods, it has obvious ad...
